What is Lithium Metal Used For?

‍Lithium is abundant in the earth’s crust, but it is difficult to mine and process. This metal is a key element in many batteries and other devices because it is so useful. It has unique properties that make it ideal for many applications. However, unprocessed lithium ore tends to be toxic and can even cause death if ingested. Lithium metal is not made from the ore, it must undergo a series of processes to become usable for specific purposes. Once mined, the lithium must be processed with heat or chemicals to extract the pure metal from the ore. There are various methods of extracting lithium from its source materials, including clay, pegmatite, and spodumene. Each of these processes has its own set of benefits and downsides. Let’s take a look at some of the most common applications of lithium metal.


Batteries are perhaps the most common use for lithium metal. There are many types of batteries that use lithium, including lithium-ion, lithium-titanate, lithium-sulfur, and lithium-polymer. Lithium-ion batteries are the most commonly used type of lithium battery and are used in cell phones, laptops, and electric cars. The lithium-ion batteries in most cell phones are generally not powerful enough to be a threat to anyone’s health. Lithium batteries have become a preferred energy source in many electronic devices because they have several advantages over other types of batteries. Lithium batteries are lighter, smaller, and have a longer lifespan than most other batteries. Additionally, they have a very low self-discharge rate, which means they retain their charge for a long time before needing to be recharged.


Lithium metal is also used in the manufacturing of many types of electronics, like laptops, cell phones, and other devices. It is often used in the circuits of these devices for its conductivity and low resistance to current flow. Lithium is often combined with other materials to make it a more useful material for manufacturing electronics. One example is the use of lithium tantalate in circuit boards. This material is commonly used in high-frequency applications and to make circuits more energy efficient.

Aerospace and Defense

Lithium is also used to make certain types of aerospace and defense equipment, such as spacecraft, satellites, and weapons. It is commonly used in batteries for these applications. One example is the space shuttle, which used lithium batteries to power its hydraulic systems. Lithium is useful for aerospace and defense applications because it is lightweight and has a long lifespan. However, lithium can be dangerous if it is not transported and stored properly, so those working with lithium-powered equipment must take proper safety precautions.

Other Uses for Lithium Metal

Lithium is also used in many other applications, including in health care products and dietary supplements. Lithium salts are often used in medicine to treat mood disorders, such as bipolar disorder. Lithium salts are also used in some water supplies to control mood disorders, including depression and bipolar disorder. Lithium is also combined with cerium, neodymium, and other rare earth metals to make strong magnets. These magnets, called neodymium magnets, are commonly used in speakers, headphones, and other devices. Lithium is also used in lithium metal oxide to make a material that is highly resistant to heat.

Limitations of Lithium Metal

Lithium is a very useful metal, but it does have some negative side effects when used in electronics. For example, lithium batteries are prone to catching fire when they are overcharged, which can cause the entire device to catch fire. There have been many incidents in which lithium ion batteries have caught fire, including an incident in 2017 when a Samsung Galaxy Note 7 phone caught fire on a Southwest Airlines flight. For this reason, lithium batteries are often used in conjunction with circuit boards that monitor and shut down the charging process when something goes wrong. However, lithium batteries also have some positive effects that make them useful in a variety of products.

Wrapping Up

Lithium is a very useful metal, but it can be difficult to work with due to its reactivity with water. Even though the properties of lithium make it a great energy source, it can be dangerous if handled improperly. Lithium is often used in batteries, and even though it can cause fires, it is a better source of energy than many other metals. In order to make lithium metal usable for specific applications, it must be carefully processed from its ore. There are several processes that can be used to extract lithium from its source material, and each has its own set of benefits and drawbacks. Lithium is a useful metal that is often used in electronics due to its lightweight properties and high energy density. It is also used in aerospace and defense applications, as well as in many other types of products.
